Motorola ATRIX 4G has an unofficial update on the Motorola’s Update Page
Motorola ATRIX 4g has an update that has been on Motorola’s page for a few days but doesn’t know why Motorola didn’t make it known. The update known as 4.1.83 on the beta test stage but that doesn’t prevent from downloading the Update.
The udate can be done manually, just head over here and select the Atrix. It’s the first one on the list. Read step three, check the box, and hit the download software update link. This will download the Motorola Updater utility.
Then connect your ATRIX via USB cable and run the updater, but take a note that Update is quite large that is 2.8GB and will take about 35minutes to complete it and make sure that your connection may not be disabled while downloading. It’s also possible that your Atrix won’t be seen by the Updater. IN that case, go into your settings and disable USB Debugging.
After achieving the update process just play with it and share your experience with us.
